Atomoxetine, a nonstimulant adrenergic agent, appeared effective for pediatric attention-deficit hyperactivity disorder, both in short- and long-term studies, according to posters presented at a meeting of the New Clinical Drug Evaluation Unit sponsored by the National Institute of Mental Health.
The action of adrenergic agents on the cardiovascular system may be potentiated by monoamine oxidase inhibitors or tricyclic antidepressants or other drugs known to prolong the QTc interval.
Over these years, he visited the emergency room 18 times, requiring drainage of the corpus cavernosa and irrigation with alpha adrenergic agents in 10 of these visits.

Connor (University of Connecticut Health Center) and Meltzer (University of Massachusetts Medical School) review the pharmacodynamics, indications, dosage, metabolism, and interactions of the stimulants, antidepressants, mood stabilizers, antipsychotics, anxiolytics, and adrenergic agents sometimes prescribed to children and adolescents.

When the standard therapy of intracavernosal adrenergic agents with/without intracavernosal aspiration irrigation does not result in detumescence, a variety of surgical shunting procedures (proximal and distal approaches) have been used to direct blood from the corpora cavernosa into the low-pressure spongiosal system.
It must be remembered that the later adrenergic agents (albuterol, bitolterol, pirbuterol, levalbuterol, salmeterol, formoterol, and arformoterol) are much more beta 2 specific than previous agents such as epinephrine and isoetherine.
The difference in salmeterol's pharmacodynamics is reflected in its pharmacokinetics with a slower onset and time to peak effect and a longer duration of action compared with previous adrenergic agents.
In addition, beta adrenergic agents have been reported to produce electrocardiogram (ECG) changes, such as flattening of the T wave, prolongation of the QTc interval, and ST segment depression.
